Dear Tammy: You should have no guilt on this one. If the diagnosis
was truly immune-mediate anemia, it is one of the least understood
diseases affecting ferrets today, and one that carries the poorest
prognosis. Immune-medicated hemolytic anemias in ferrets arise for
unknown reasons, and commonly appear so quickly, that significant
loss of blood cell mass occurs before any signs are noticed. A
ferret can actually digest its red blood cells to a life-threatening
level within 72 hours.

The treatment for this condition is heavy immunesuppression with
corticosteroids and even stronger medications, and it is rarely

The use of oxyglobin in this case shows the levels that you went to
save her. However, synthetic hemoglobins are best employed when an
insult has passed and the body just needs support until its marrow
regenertive capacity kicks in. When used in the face of a hemoytic
crisis, it simply affords the animal a little more time. Very few
cases of hemolytic anemia in ferrets ever show a regenerative

I am sorry for your loss - but you shoul rest easier in knowing that
the vast majority of AIHA cases in ferret don't respond to anything
(or at least we're still trying to find something that works well on
